APPARATUS FOR PRODUCING-CRYSTAL ICE.

SPECIFICATION forming part of. Letters Patent No. 617,849, dated January 17, 1899. Application filed line 18, 1898. Serial No. 683,891. (No model.)

To all whom it may concern:

Be it known that I, FRANZ BOES, a subject of the King of Ifrussia, Emperor of Germany, residing'at Dgs'seldorf, Kingdom of Prussia,

' Empire bf Gefinanxhave invented a certain new and'usefulldpparatus for the Production of Crystal Ice, of which the following is ,a specification.

The'present invention relates to an appa- 19 ratus for the production of crystal ice out of the waste steam leaving the steam-engine.

Figure 1 of the'acoompanying drawings is a longitudinalsection of the apparatus with its! parts. Fig. 2 is a cross-section of the r'g-same. Fig. 3' is the plan of the condensation- -1F o om from which the cover-plate is removed.-

co r-plate removed. The steam to be used comes from the steam- 26 engine and passes through tube B into a piping r 73; which is provided with outlet-nozzles d d, arranged at suitable distances. Through these outlets the steam is driven between the angular walls of the cooling vessel K, where it con- 2'5 denses. The action of the nozzles into the angls is especially advantageous,becauseit produces a rebounding movement of the quantity of steam introduced and filling the space. In consequence of this arrangement of the cool- 36 ing surfaces, which enables the utilization of the whole surfaces, a great saving of room is obtained. The water deposited from the steam collects in the lower part of the box K, surrounding the cooling-surfaces K, and passes 5 through pipe to into the upper distributionchamber F of the filter-box F. From here it flows through the communicating pipes f over the filters F passes through the same, rises in the pipes g, of which'the lower end is of c conical shape, and streams through the lat- .eral openings g into the collecting-room G,

X from where it passes through a filter of any n itable construction V into the proper ice- ---'cells.fl Besidc's, the filter rising-pipes g are 5 providedwith traversing cylinder-pipes 9 above the outlets 9, leading outside and pro vided with tap 71.. Any particles of oil which may have got into the filte'rjroln the rising- I pipesg enter into these pipes Zf.\ lhere they so collect and can be let off through h.

This-arrangement also enarlm a convenlc is contro mlcapparatus.

is the plan ofv the filter-room with the r Anotherimportantimprovement is the cool ing of the filter, which is efiected by thecooling-water let in through 0 and adapted to be run around the filter-chambers Fflprincipally in serpentine windings. The action of the filter is thus rendered much better.

The filter-chambers F are not brought up closely to each other and to the walls of the box F, but there is some space left between their walls as well as at the bottom,'so that all surfaces of the filter-chambers are cooled. From there the cooling-water ascends through pipe 4 into the angular cooling vessel K, streams through the same, and leaves the ap-' 'paratus through pipe '17..

.1 The arrangement of the collecting-room G between thedistributing-room F and the filter-chambers F is new and of favorable ef- 76 feet upon the function of the apparatus, in asmuc h as through the cooling of the walls in upward and downward direction and through the communicating pipe f the cooled water itself efiects a previous cooling pf the water streaming to the filtering material Having now described my invention,what I claim as new, and desire to secure by Letters Pate it, is-

An apparatus for the production of crystal 8o ice consisting of-a condenser with closed boxv K, inside with angular cooling vessel K, water-inlet pipe water-outlet pipe, steam-inlet R, annular distributing-pipe 'r with nozzles d d opposite the angles of the said 0001- ing vessel K, and a filtering apparatus with alternate, cooled filter-chambers F, the distributing-room F feeding the chambers F, with supply-pipes f passing through'the collecting-room G, rising-pipes 9 out of the fil-v 9o ter-chamber F with outlets .g situated inside the collecting-room, connecting-pipe g arranged above the latter g with tap it situated outside, and an after filterV with filtering' material arranged between sieves, sub stantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
